内容摘要
本书包括六章内容,可分为三个部分。第一部分(第二章)从海洋油气导管的功能入手,按照油气导管所处作业环境,将其分为水上井口和水下井口两类,分别重点介绍这两大类井口的探井和开发井油气导管主要组成及其结构特点,并给出国际典型的浅水和深水井口装置结构。第二部分(第三、四、五章)主要以海洋油气导管安装为目标,分别论述了海洋油气井安装油气导管的三种主流方法(分别是:钻入法、锤入法和喷射法)的施工工艺和装备,同时重点介绍了三种海洋油气导管安装方法的关键设计技术。在第一和第二部分基础上,第三部分结合地质、海洋环境和施工作业因素,重点分析了三种施工工艺的差异性和彼此的适用性,可为海洋油气导管安装方法选择提供科学依据。
